This PR adds a new interface to control how SegmentMetadataCache chooses ColumnType when faced with differences between segments for SQL schemas which are computed, exposed as druid.sql.planner.metadataColumnTypeMergePolicy and adds a new 'least restrictive type' mode to allow choosing the type that data across all segments can best be coerced into and sets this as the default behavior.
This is a behavior change around when segment driven schema migrations take effect for the SQL schema. With latestInterval, the SQL schema will be updated as soon as the first job with the new schema has published segments, while using leastRestrictive, the schema will only be updated once all segments are reindexed to the new type. The benefit of leastRestrictive is that it eliminates a bunch of type coercion errors that can happen in SQL when types are varied across segments with latestInterval because the newest type is not able to correctly represent older data, such as if the segments have a mix of ARRAY and number types, or any other combinations that lead to odd query plans.
* Expr getCacheKey now delegates to children
* Removed the LOOKUP_EXPR_CACHE_KEY as we do not need it
* Adding an unit test
* Update processing/src/main/java/org/apache/druid/math/expr/Expr.java

* Make resources an ordered collection so it's deterministic.
* test cleanup
* fixup docs.
* Replace deprecated ObjectNode#put() calls with ObjectNode#set().
Currently, there is no way to run ITs if unit-tests fail on coverage. This PR allows Revised, Standard ITs to run even when unit-tests fail on coverage errors, still failing the workflow. This PR also fixes existing GHA workflow naming.

* Fixing an issue with filtering on a single dimension by converting In filter to a selector filter as needed with Filters.toFilter
* Adding a test so that any future refactoring does not break this behavior
* Made comment a bit more meaningful
The "new" IT framework provides a convenient way to package and run integration tests (ITs), but only for core modules. We have a use case to run an IT for a contrib extension: the proposed gRPC query extension. This PR provides the IT framework functionality to allow non-core ITs.
* Be able to load segments on Peons
This change introduces a new config on WorkerConfig
that indicates how many bytes of each storage
location to use for storage of a task. Said config
is divided up amongst the locations and slots
and then used to set TaskConfig.tmpStorageBytesPerTask
The Peons use their local task dir and
tmpStorageBytesPerTask as their StorageLocations for
the SegmentManager such that they can accept broadcast
segments.
Changes:
- Replace `OverlordHelper` with `OverlordDuty` to align with `CoordinatorDuty`
- Each duty has a `run()` method and defines a `Schedule` with an initial delay and period.
- Update existing duties `TaskLogAutoCleaner` and `DurableStorageCleaner`
- Add utility class `Configs`
- Update log, error messages and javadocs
- Other minor style improvements
* queue tasks if all slots in use
* Declare hamcrest-core dependency
* Use AtomicBoolean for shutdown requested
* Use AtomicReference for peon lifecycle state
* fix uninitialized read error
* fix indentations
* Make tasks protected
* fix KubernetesTaskRunnerConfig deserialization
* ensure k8s task runner max capacity is Integer.MAX_VALUE
* set job duration as task status duration
* Address pr comments

Instead of downloading jdk everytime we run CI, we're using inbuilt temurin jdk distributions 8, 11, 17 by settiing JAVA_HOME variable. This is not working as expected since we were not setting this as global environment variable as a result all CI builds are running on jdk11. This PR fixes the issue.
